    Repair Log: CPS1 No Sound

    Good job there! So even after probing the Z80, the RAM was still suspected to be at fault? It goes to show... I need to repair a board which plays sound fine on boot but plays random SFX and music. I don't have the skills to probe the board so will change the Z80 for a Z80a.

    CPS2 multi hangs at rom check

    I've got an A board behaving like this. I believe it's to do with the Q sound, perhaps it's not making a proper connection between A and B.

    DARKSOFT CPS1 Multi - Support thread

    I think it is a compatibility issue. The A board I was having issues with, works totally fine a legit SF2CE.

    DARKSOFT CPS1 Multi - Support thread

    So it turns out after the recap, I get beefier sound, but the BGM still cuts out for me. On mercs, it’s always within 10 seconds. On other games it’s random. I’ve read on another forum that it could be the YM3012, z80 chip or the OKI or the sound crystal. So… someone mentioned on another...

    I forgot to mention that all the q sound games worked without issue for me too.

    It sounds the same behaviour, it was driving me mad! I even ordered an expensive genuine a board to test SF2CE but looks like it will be surplus when it arrives. If your board is an Ali board, which I reckon it is, recap the board and go from there. Test on your blast city. The crust most...

    Hey, so I've recapped the board, and have it running stable at 4.9v. WOW, I'm hearing SFX I never did before. Thanks everyone who replied.
